PostPosted: Sun Jun 01, 2008 5:20 pm    Post subject: Plan for upgrading motherboard Reply with quote

My motherboard has died, and I'm going to replace it with an Intel based chipset (PK5 Pro). I'm sacrificing SLI for stability.

Anyway, I know my kernel is customized for the nvidia 680 chipset, (I don't use initramfs) and of course the new motherboard will be an Intel P35 chipset so I suspect it's not going to be able to mount the root device.

To solve this I'm planning on booting from a Gentoo live CD, and getting it to mount the existing system. Then from there, compile the kernel again, with the appropriate drivers.

Does anyone see any problems with this approach? Anybody think of an easier way?

I've having to use my (very old) mac mini to post this, and boy it's slow.

No, that's pretty much how I did it when I moved from a PII to a Core2 Duo, in the short time it remained 32 bit after the change. The only thing that would make it easier is if your old mobo would resurrect itself long enough to allow you to compile the kernel for the new mobo, then die again for the last time.

Good luck.

Blessed be!

Yup - You just need a working kernel from anywhere and you're pretty much there!
Maybe a couple of other stuff like re-doing lm_sensors if you use it, but that's it! :D

Try doing that with Windows... Welcome to BSOD city! :P

I've been trying the old motherboard every day in hope - I only need half an hour... but nothing so far. I'll keep people posted when I do the upgrade.
